These have both been with him since his arrival, and they seem to be women of excellent character. The professor is writing a learned book, and he found it necessary, about a year ago, to engage a secretary. The first two that he tried were not successes, but the third, Mr. Willoughby Smith, a very young man straight from the university, seems to have been just what his employer wanted. His work consisted in writing all the morning to the professor's dictation, and he usually spent the evening in hunting up references and passages which bore upon the next day's work. This Willoughby Smith has nothing against him, either as a boy at Uppingham or as a young man at Cambridge. I have seen his testimonials, and from the first he was a decent, quiet, hard-working fellow, with no weak spot in him at all. And yet this is the lad who has met his death this morning in the professor's study under circumstances which can point only to murder."
